A man and woman were charged Friday in a Christmas Day pursuit crash that killed two minivan passengers - including an 11-year-old Daly City boy - at a Pasadena intersection.

Darrell Lee Williams, 22, and Brittany Michelle Washington, 21, were charged with murder, after originally being arrested on vehicular manslaughter charges. The alleged gang members face arraignment Friday in Pasadena Superior Court.

Williams was allegedly driving a Dodge Durango sport utility vehicle Tuesday with Washington in the front seat and two other passengers. After a traffic violation, Williams failed to stop for police and led officers on a brief pursuit that ended with a crash near the 210 Freeway and Marengo Avenue, according to prosecutors.

Tracey Ong Tan, 25, of Glendale, and Kendrick Ng, 11, from Daly City -- both passengers in the minivan -- were killed in the crash. Three other passengers - all Ng relatives - suffered injuries. They are Kendrick Ng, 49, Irene Ng, 52 and a 16-year-old, all from Daly City. The family's godfather, Dennis O'Connor told NBC Bay Area that the family was in Southern California for Christmas.

Williams, a Pasadena resident, and Washington, of Los Angeles, were charged with two counts each of murder, three counts each of assault with a deadly weapon and one count each of felon in possession of a firearm.

The crash occurred hours after the shooting death of Victor McClinton, a Los Angeles County Sheriff's Department employee and youth sports coach described by friends and residents as a "mentor" and beloved member of the community. Another man was wounded in the shooting.

McClinton, a 49-year-old father of two, was not the target, according to police.

Police were attempting to determine whether the vehicle involved in a crash that killed two people late Tuesday was the same vehicle described by shooting witnesses. Also, investigators retrieved a firearm discarded during the chase, according to a police statement.

Ballistics tests, which might require weeks to complete, will help determine whether the gun was used in both incidents.

"We have parts of the puzzle but we are looking to put all that together so that we could ultimately identify the persons responsible," Pasadena Police Chief Phillip Sanchez said Thursday.
